Subject: cxgb4: fix MAC address hash filter
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ce9aeb583a1071304d0e4ab8db600bfc8a6a1b44;p=linux-beck.git

cxgb4: fix MAC address hash filter

Fix the calculation of the inexact hash-based MAC address filter.
It's 64 bits but current code is missing a ULL.  Results in filtering out
some legitimate packets.
